Sheath for radiators and the like



May 21, 1935. F. w. HVOSLEF SHEATH FOR RADIATORS AND THE LIKE Filed Dec. 23, 1933 Patented May 21 1935 ICE I 4 Claims.

My invention relates to an improved sheath for radiators and the like, and the objects of my invention are, first, to provide a sheath for a radiator of the convector type which will form a conduit to draw air past and through the radiator; second, to provide such a sheath which allows vertical adjustment of the radiator and of the horizontal pitch thereof; and third, to provide means for regulating the volume of air drawn past the radiator.

I attain these objects by the structure illustrated in the accompanying drawing, in which Figure 1 is a front perspective View of the sheath.

in position upon a radiator; Fig. 2, an end elevation thereof; Fig. 3, a plan view of a portion of the sheath; and Fig. 4, a front elevation thereof.

Similar numerals refer to similar parts throughout the several views.

The structure is designed for use in connection with a radiator, designated by the numeral I a in the drawing, which is of the convector type,

that is adapted to heat by means of convection currents of heated air rather than by direct radiation, and preferably comprises acentral portion forming a conduit for the passage of the heating medium and fins extending therefrom, said fins being spaced to allow the passage of air therebetween.

The sheath is comprised of a back portion 2, a pair of end portions 3, and a hinged top or damper portion 4.

The end portions 3 are substantially rectangular in form and are approximately the same width as the radiator, but of considerably greater height than the height of the radiator. Each of the end portions 3 is provided with a central, longitudinally extending slot 5 and a pair of longitudinally extending slots 6 spaced on each side thereof.

- The back portion 2 is bolted or otherwise se-' cured to the end portions 3 and is provided with a plurality of hinges I by which the top portion 4 is secured thereto.

The manner of use of the sheath is as follows: The sheath is assembled, as indicated above, and the radiator I positioned therein as shown in Fig. 1. The radiator I is held in position by means of bolts 8 extending from the radiator through the slots 6. The necessary nipple connections from the inlet pipe 9 and the outlet pipe ID are made through the slots 5, in the end portions 3. The slots 5 and 6 extending longitudi nally of the end portions 3 allow of adjustment of the radiator up and down and" allow one end to be raised above the other, if desired, as indi- 1 damper.

cated by the dotted line of Fig. 4, so that circulation through the radiator may be facilitated.

The entire radiator and sheath are designed to be installed in an aperture in the wall I2 of the room to be heated. The aperture l I is closed by a panel I3 of metal or other suitable material, which also acts as a closure for the front of the sheath. The panel I3 is provided near its top with a grille I I and at its bottom (not shown) is spaced somewhat above the bottom of the aperture II to allow entrance of air.

The hinged top 4 is adapted to be manipulated by a chain I5 or other suitable means to act as a The air passing in at the bottom of the panel I3, is forced to pass upwardly over the radiator I, is'heated and rises, passing out the grille I4. The amount of air passing over the radiator is controlled by the manipulation of the top or damper portion 4. r

It will be noted that all of the air drawn by convection into the apparatus is forced to pass directly over or through the radiator I, thus a more eflicient heating is obtained than where, as is now customary, the radiator is positioned in the aperture, which must be longer than the radiator to permit the installation of the inlet pipes 9 and Ill and the necessary shut-off valve, and much of the air drawn into the aperture follows the path of least resistance around the ends of the radiator instead of through it, with consequent loss of heating efiiciency.

It will be understood that the top or damper portion 4 may be omitted if its functions are not desired. The back portion 2, may also be omitted, particularly when the aperture I2 is the same depth as the width of the radiator I so that the back of the aperture itself replaces the back portion 2. In this case only the end portions 3 are used and perform the double function of providing an adjustable support for the radiator and preventing convection currents of air from being drawn past the ends of the radiator.

I claim: I

1. A radiator sheath adapted to enclose a radiator and comprising a pair of end portions, each of said end portions being provided with a longitudinal slot adapted to allow passage of a connecting nipple therethrough, and a plurality of longitudinal slots each adapted to allow passage of a bolt therethrough whereby to support said radiator in said sheath; a back portion attached to said end portions; a top portion hingedly attached to said back portion, and means for actuating said top portion to act as a damper.

2, A radiator sheath adapted to enclose a radiator and comprising a pair of end portions, means comprising a pair of bolts extending through longitudinal slots in each of said end portions for attaching said radiator to said end portions whereby to permit vertical adjustment of either end of said radiator; a slot in each of said end portions adapted to permit passage therethrough of a nipple connection, a back portion attached to said end portions, a hinged top portion, and means for actuating said topportion to act as. a dampen. m

3. In combination, a radiator sheath adapted to enclose a radiator and to be installed with said radiator in a recess or aperture in the wall of a room or the like, said sheatlr'cempri'sihg -a pair" of end portions, a back portion, and a hingedtop portion, means for operating said hinged top por tion to act as a damper, and a panel adapted to close said aperture in the room and also the front of said sheath, said panel being spaced above the bottom of the aperture and provided near its upper extremity with a grille.

4. Supporting means for radiators and the like comprising a body portion of a width substantially similar to the width of the radiator to be supported and height substantially greater than the height of said. radiator, said, body portion being: provided With a longitudinally extending slot adapted to permit the insertion therethrough oonnections for a heating medium to said radi-
